Inganda zitumanaho za laser ziratera imbere byihuse kandi zigiye kwinjira mugihe cyizahabu cyiterambere

Itumanaho rya Laser ni ubwoko bwitumanaho ukoresheje laser kugirango wohereze amakuru. Laser ni ubwoko bushya bwaisoko yumucyo, ifite ibiranga umucyo mwinshi, ubuyobozi bukomeye, monochromism nziza hamwe nubufatanye bukomeye. Ukurikije uburyo butandukanye bwo kohereza, burashobora kugabanywamo ikirereitumanaho rya lasern'itumanaho rya fibre optique. Itumanaho rya Atmospheric ni itumanaho rya laser ukoresheje ikirere nk'ikwirakwizwa. Itumanaho rya fibre optique nuburyo bwitumanaho ukoresheje fibre optique kugirango wohereze ibimenyetso bya optique.

Sisitemu y'itumanaho rya laser igizwe n'ibice bibiri: kohereza no kwakira. Igice cyohereza kigizwe ahanini na laser, Optical modulator na antenna yohereza optique. Igice cyo kwakira kirimo ahanini optique yakira antenne, optique iyungurura naPhotodetector. Ibisobanuro bigomba koherezwa kuri aModeri nzizaihujwe na laser, ihindura amakuru kurilaserakayohereza hanze binyuze muri optique yohereza antenne. Ku iherezo ryakira, optique yakira antenne yakira ibimenyetso bya laser ikayohereza kuriicyuma gipima, ihindura ibimenyetso bya laser mubimenyetso byamashanyarazi ikabihindura amakuru yumwimerere nyuma yo kwongerwaho na demodulation.

Buri cyogajuru muri gahunda ya Pentagon giteganijwe guhuza imiyoboro ya mesh itumanaho irashobora kugira imiyoboro igera kuri ine kugirango bashobore kuvugana nizindi satelite, indege, amato hamwe na sitasiyo.Ihuza ryizahagati ya satelite ni ingenzi cyane kugirango intsinzi y’inyenyeri zo mu kirere z’ingabo z’Amerika zuzuze isi, izakoreshwa mu itumanaho ry’amakuru hagati y’imibumbe myinshi. Laser irashobora gutanga amakuru yikwirakwizwa ryinshi kuruta itumanaho rya RF, ariko kandi ihenze cyane.

Igisirikare cy’Amerika giherutse gutanga hafi miliyari 1.8 z’amadolari y’amasezerano ya gahunda ya 126 y’inyenyeri izubakwa ukwayo n’amasosiyete yo muri Amerika yateje imbere ikoranabuhanga ry’itumanaho rya optique ryo gukwirakwiza amakuru kuri interineti rishobora gufasha kugabanya ikiguzi cyo kubaka inyenyeri mukugabanya cyane ibikenewe byanyuma. Ihuza rimwe-ryinshi rigerwaho nigikoresho cyitwa imiyoboro ya optique itumanaho (MOCA muri make), ikaba idasanzwe kubera ko ari modular cyane, kandi MOCA icunga itumanaho rya optique ituma imiyoboro ihuza imiyoboro ya interineti ishobora kuvugana na izindi satelite nyinshi. Mu itumanaho rya laser gakondo, ibintu byose ni ingingo-ku-ngingo, umubano umwe-umwe. Hamwe na MOCA, imiyoboro ihuza interineti irashobora kuvugana na satelite 40 zitandukanye. Iri koranabuhanga ntabwo ari inyungu gusa yo kugabanya ikiguzi cyo kubaka inyenyeri zo mu kirere, niba ikiguzi cya node kigabanutse, hari amahirwe yo gushyira mubikorwa inyubako zitandukanye bityo urwego rwa serivisi zitandukanye.

Hashize igihe, icyogajuru cya Beidou cyo mu Bushinwa cyakoze ubushakashatsi bwitumanaho rya laser, bwohereza ibimenyetso muburyo bwa lazeri kuri sitasiyo yakira ku butaka, bifite akamaro gakomeye mu itumanaho ryihuse hagati y’imiyoboro ya satelite mu gihe kiri imbere, gukoresha laser itumanaho rishobora kwemerera icyogajuru kohereza megabits ibihumbi namakuru kumasegonda, umuvuduko wubuzima bwa buri munsi ni megabits nkeya kugeza kuri megabit icumi kumasegonda, kandi itumanaho rya laser rimaze kugaragara, Umuvuduko wo gukuramo ushobora kugera kuri gigabayiti nyinshi kumasegonda, kandi mugihe kizaza irashobora no gutezwa imbere muri terabaýt.

Kugeza ubu, gahunda yo gutwara abantu mu Bushinwa ya Beidou yashyize umukono ku masezerano y’ubufatanye n’ibihugu 137 ku isi, ifite uruhare runini ku isi, kandi izakomeza kwaguka mu gihe kiri imbere, nubwo Ubushinwa bwo mu bwoko bwa Beidou bwo mu Bushinwa aribwo bwa gatatu bwa sisitemu yo kugendana ibyogajuru bikuze, ariko ifite umubare munini wa satelite, ndetse urenze umubare wa satelite ya sisitemu ya GPS. Kugeza ubu, uburyo bwo kugenda bwa Beidou bugira uruhare runini haba mu gisirikare ndetse no mu gisivili. Niba itumanaho rya laser rishobora kugerwaho, rizazana inkuru nziza kwisi.
